The Lynx 5000 positions the yellow rangefinder image horizontally by moving the small lens located near the beamsplitter. This lens is linked to the rear of the lens body through a pivot rod. The effective length of the rod can be varied with an eccentric screw on the top side of the rangefinder. The length of the rod determines how far the small lens moves for a given front-rear focus movement of the lens body. In the picture below, the adjustment is dentified with an arrow. The moving lens is just below it: Linearity adjustment I suspect this adjustment must be reset whenever the beamsplitter is replaced. Any deviation whatsoever of the beamsplitter from the original angle (~45 degree) will require adjusting this screw. Note that this adjustment affects both infinity and close focus. Therefore, it is necessary to alternate between the linearity screw and main horizontal adjustment screw until the rangefinder and lens are in agreement at both infinity and minimum focus. A photo of the main adjustment can be found here: Main horizontal RF adjustment (courtesy Dan Mitchell) Hope this helps someone else to restore one of these classics!
